Application filed June 17, 1918. Serial No. 240,341.

To all whom it may concern:

Be it known that I, HERBERT A. WIM- PERIS, a citizen of the United States, residing at Minneapolis, in the county of Hennepin and State of Minnesota, have invented certain new and useful Improvements in Spring-Oilers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention has for its object to provide an extremely simple and highly efficient automatic oiling device for automobile springs or other springs of the multiple leaf type; and to such ends, it consists of the novel construction and combination of parts hereinafter described and defined in the claim.

The device comprises a casing formed with a pad pocket and a small oil well. An absorbent pad of felt, or the like, is placed'in the pad pocket and the casing is clamped to the spring with the distributing pad pressed tightly against the leaves of the spring at one side. The oil well has one or more oil feeding ports located far above its bottom, and preferably close to its top and there is also preferably a deflecting lip for directing the oil, under a splashing action through the port and against the pad. The oiling device may be applied to one or both sides of the spring.

In the accompanying drawings whichv illustrate the present form of the improved oiling device,

Figure 1 is a side elevation showing an automobile spring of the Ford type having two of my oiling devices applied thereto;

Fig. 2 is an enlarged side elevation of the oiling device; and

Fig. 3 is a transverse section taken on the lines 8-3 of Figs. 1 and 2.

The multiple leaf spring is indicated, as an entirety, by the numeral 4. The casing of the oiling device is indicated, as an entirety, by the numeral 5. Preferably, 1t 1s form and provided with an inner partition 6 that divides the same into the above noted oil well 7 and into a pad pocket which holds the absorbent or felt pad 8. In its top, the well 7 is provided with a filhng neck 9 closed by a suitable cap 10. In the partition 8 is the noted oil delivery port 11, preferably formed by pressing a deflecting lip 12 into the well. At top and bottom, the casing 5 is provided with perforated ears 13. Nut equipped bolts 14 pass through the ears 13 and through perforated end of the clamping bar 15, tightly clamp said bar 15 and the pad 8 against the sides of the spring. The side walls of the pad receiving pocket are preferably cut back and formed with curved edges 16, as indicated by dotted lines in Fig. 3. In Fig. 3, these edges 16 do not quite engage the springs, but when the bolts are tightened, a little more than shown, these edges 16, at their intermediate portions only, will engage the edges of the intermediate leaves of the spring 4, and then afford solid resist ance for the bolted oiler, however, causing or tending to cause the casing or oilin device to creep either upward or downwar under the spring action, and resulting movement of the leaves of the spring.

The oil y contained in the well 7 should not be much above the bottom of the de livery port 11 and may be much below the same. Hence, when the spring is at rest, there will be no oil feeding action. When, however, the spring is in motion, there will be a splashing of oil and the oil willsplash through the port 11 and keep the absorbent distributing pad 8 supplied with a lubricant. The lip 12 greatly facilitates or insures the delivery of oil to the pad. As the pad is tightly pressed against the partition 6, around the port- 11, surplus oil will be caused to immediately run back into the oil Well.

Oil delivered to the distributing pad 8 will be delivered between the leaves of the spring and will work between the leaves, keeping the same well lubricated with a minimum amount of oil.

Actual practice has demonstrated the operativeness and practicability of this device. Obviously, the oiling device may be applied to both sides of the leaves of the spring simply by omitting the clamping bar 15 and substituting a second oiling device on that side of the spring, using the same bolts 14 to connect the two oiling devices.

What I claim is:

The combination with a multiple leaf spring, of a device comprising an oil wellhaving means for clamping the same to one side of said spring, said Well having In testimony whereof I aflix my signaan oil delivery port located above its oil ture in presence of tWo Witnesses.

level, an oil distributing pad clamped between the side of the spring and the adjacent side of said Well and covering said port, and a deflecting lip projecting into the Well from the lower edge of said port.
